My CRKT Crawford Falcon is my go to abuse the heck out of it blade, sharpened so often the serrations are almost gone. I also carry a Benchmade Tanto (HK) (discontinued) that rarely is used, but the heft, balance and edge are truly inspiring. I also love the Axis lock. The last I carry is a CLB Boker that is small and light and has never been deployed.
So I use a $40 blade everyday, and leave the others for more special occasions, what ever they might be. The CRKT has provided a longer service life than expected, and when I lost a clip screw CRKT sent me a new clip and screws pronto.
